Hearing detection system and method

Abstract

The invention discloses a hearing detection system, which comprises a hearing tester used for hearing detection, a vision amplification system used for visual stimulation and an acoustic generator, wherein the hearing tester controls the acoustic generator to product sound; and the vision amplification system is connected with the acoustic tester in a wired or wireless mode. The invention also discloses a method adopting the hearing detection system for hearing detection, which comprises the following steps: when the hearing tester receives a start signal, controlling the acoustic generator to produce the sound; when the acoustic generator produces the sound, starting the vision amplification system if a tested person has listening reaction; displaying a picture by an electronic display of the vision amplification system to cause the tested person to be guided to turn to watch the picture; when the acoustic generator stops generating sound and the display stops displaying, ensuring that the tested person turns back; repeating the above steps until the tested person builds the conditioned reflex of turning to watch the picture of the display when the tested person hears the sound; ensuring that the audio frequency and the intensity of the acoustic generator are gradually changed; and when the tested person turns to watch the picture of the display because of the conditioned reflex, recording the audio frequency and the intensity at the moment.

Description

technical field [0001] The invention relates to the field of hearing detection technology, in particular to a hearing detection system and method. Background technique [0002] Visual reinforcement audiometry is a behavioral audiometry method for infants aged 7 to 30 months. It is widely used in foreign audiology circles, but it has not been popularized in China. [0003] When testing the audiology of infants aged 7 to 30 months, the infants cannot cooperate with the hearing to respond to the sound (such as raising hands or placing toys, etc.); it can be used at the same time through the sound field speaker to ensure that the sound intensity of the infant can be heard The light box provides visual stimulation to it. After the combination of sound and light stimulation is presented many times, the child will establish a conditioned reflex of looking for light stimulation when he hears the sound; When looking for light stimulation, give out light stimulation immediately to re...

Problems solved by technology

[0004] However, the light box used in the audiometry system is expensive, and the supply is small, so it is often necessary to make it by yourself; and the sound field is generally small, but most of the space is occupied by the light box; the single toy in the light box may cause some children to be interested in the display. The toy is not interested or afraid; and the light box is too bulky to carry and move
